Dehydro Benidipine is a desaturated analog of Benidipine, featuring a conjugated diene system in place of the parent compound’s dihydropyridine core. This structural modification introduces a trans-double bond between C4 and C5 positions, while retaining nitrophenyl substitution at the 3-position and methoxy groups at the 4- and 6-positions of the pyridine ring. The compound arises as a synthetic byproduct during oxidative dehydrogenation steps in Benidipine production. It serves as a reference standard for HPLC-based impurity profiling in quality control of Benidipine APIs.
